EN 713:1993 Plastics Piping Systems - Mechanical Joints Between Fittings and Polyolefin Pressure Pipes - Test Method for Leaktightness Under Internal Pressure of Assemblies Subjected to Bending
This European Standard specifies a method for checking the leaktightness under internal hydrostatic pressure of assembled mechanical joints (excluding fusion-welded joints) between fittings and polyolefin pressure pipes while subjected to bending.It details a calculation method for the average bending radius and the procedure for achieving this bending (see note).Checking of the leaktightness under internai pressure is carried out in accordance with the method given in EN 715.The test method is applicable regardless of the design and material of the fitting used for jointing pipes.
